The disclosure may be applied to a technology of managing connections between a terminal supporting a multi-subscriber identity module (multi-SIM) equipped with a smart secure medium and a plurality of activated telecom bundles, and connections between the terminal supporting the multi-SIM and a plurality of profiles in a single telecom bundle.
This application is based on and claims priority under 35 U.S.C. § 119 to Korean Patent Application No. 10-2020-0180213, filed on Dec. 21, 2020, in the Korean Intellectual Property Office, the disclosure of which is herein incorporated by reference in its entirety.
BACKGROUND 1. FieldThe disclosure relates to a method and apparatus for managing authentication and subscription information in a wireless communication system.
2. Description of Related ArtIn order to meet the demand for wireless data traffic soaring since the 4G communication system came to the market, there are ongoing efforts to develop enhanced 5G communication systems or pre-5G communication systems. For the reasons, the 5G communication system or pre-5G communication system is called the beyond 4G network communication system or post LTE system.
For higher data transmit rates, 5G communication systems are considered to be implemented on ultra-high frequency bands (mmWave), such as, e.g., 70 GHz. To mitigate pathloss on the ultra-high frequency band and increase the reach of radio waves, the following techniques are taken into account for the 5G communication system: beamforming, massive multi-input multi-output (MIMO), full dimensional MIMO (FD-MIMO), array antenna, analog beamforming, and large scale antenna.
Also being developed are various technologies for the 5G communication system to have an enhanced network, such as evolved or advanced small cell, cloud radio access network (cloud RAN), ultra-dense network, device-to-device (D2D) communication, wireless backhaul, moving network, cooperative communication, coordinated multi-point (CoMP), and interference cancellation.
There are also other various schemes under development for the 5G system including, e.g., hybrid FSK and QAM modulation (FQAM) and sliding window superposition coding (SWSC), which are advanced coding modulation (ACM) schemes, and filter bank multi-carrier (FBMC), non-orthogonal multiple access (NOMA) and sparse code multiple access (SCMA), which are advanced access schemes.
The Internet is evolving from the human-centered connection network by which humans create and consume information to the Internet of Things (IoT) network by which information is communicated and processed between things or other distributed components. Another arising technology is the Internet of Everything (IoE), which is a combination of the Big data processing technology and the IoT technology through, e.g., a connection with a cloud server. To implement the IoT, technology elements, such as a sensing technology, wired/wireless communication and network infra, service interface technology, and a security technology, are required. There is a recent ongoing research for inter-object connection technologies, such as the sensor network, Machine-to-Machine (M2M), or the Machine-Type Communication (MTC). In the IoT environment may be offered intelligent Internet Technology (IT) services that collect and analyze the data generated by the things connected with one another to create human life a new value. The IoT may have various applications, such as the smart home, smart building, smart city, smart car or connected car, smart grid, health-care, or smart appliance industry, or state-of-art medical services, through conversion or integration of existing information technology (IT) techniques and various industries.
Thus, there are various ongoing efforts to apply the 5G communication system to the IoT network. For example, the sensor network, machine-to-machine (M2M), machine type communication (MTC), or other 5G techniques are implemented by schemes, such as beamforming, multi-input multi-output (MIMO), and array antenna schemes. The above-mentioned application of the cloud radio access network (RAN) as a Big data processing technique may be said to be an example of the convergence of the 5G and IoT technologies.
Wireless communication technologies have been developed mainly for human services, such as voice, multimedia, and data communication. As 5th-generation (5G) communication systems are commercially available, connected devices are expected to explosively increase and to be connected to a communication network. Examples of things connected to a network may include vehicles, robots, drones, home appliances, displays, smart sensors installed in various infrastructures, construction machinery, and factory equipment. Mobile devices will evolve into various form factors, such as augmented reality glasses, virtual reality headsets, and hologram devices. In the 6th-generation (6G) era, efforts are being made to develop an enhanced 6G communication system to provide various services by connecting hundreds of billions of devices and things. For this reason, the 6G communication system is called a beyond 5G system.
In the 6G communication system expected to be realized around year 2030, the maximum transmission rate is tera (i.e., 1000 gigabit) bps, and the wireless latency is 100 microseconds (pec). In other words, the transmission rate of the 6G communication system is 50 times faster than that of the 5G communication system, and the wireless latency is reduced to one tenth.
To achieve these high data rates and ultra-low latency, 6G communication systems are considered to be implemented in terahertz bands (e.g., 95 gigahertz (95 GHz) to 3 terahertz (3 THz) bands). As the path loss and atmospheric absorption issues worsen in the terahertz band as compared with millimeter wave (mmWave) introduced in 5G, technology that may guarantee signal reach, that is, coverage, would become more important. As major techniques for ensuring coverage, there need to be developed multi-antenna transmission techniques, such as new waveform, beamforming, massive multiple-input and multiple-output (MIMO), full dimensional MIMO (FD-MIMO), array antennas, or large-scale antennas, which exhibit better coverage characteristics than radio frequency (RF) devices and orthogonal frequency division multiplexing (OFDM). New technologies, such as a metamaterial-based lens and antennas, high-dimensional spatial multiplexing technology using an orbital angular momentum (OAM), and a reconfigurable intelligent surface (RIS), are being discussed to enhance the coverage of the terahertz band signals.
For 6G communication systems to enhance frequency efficiency and system network for 6G communication systems include full-duplex technology, there are being developed full-duplex technology in which uplink and downlink simultaneously utilize the same frequency resource at the same time, network technology that comprehensively use satellite and high-altitude platform stations (HAPSs), network architecture innovation technology that enables optimization and automation of network operation and supports mobile base stations, dynamic spectrum sharing technology through collision avoidance based on prediction of spectrum usages, artificial intelligence (AI)-based communication technology that uses AI from the stage of designing and internalizes end-to-end AI supporting function to thereby optimize the system, and next-generation distributed computing technology that realizes services that exceed the limitation of the UE computation capability by ultra-high performance communication and mobile edge computing (MEC) or clouds. Further, continuous attempts have been made to reinforce connectivity between device, further optimizing the network, prompting implementation of network entities in software, and increase the openness of wireless communication by the design of a new protocol to be used in 6G communication systems, implementation of a hardware-based security environment, development of a mechanism for safely using data, and development of technology for maintaining privacy.
Such research and development efforts for 6G communication systems would implement the next hyper-connected experience via hyper-connectivity of 6G communication systems which encompass human-thing connections as well as thing-to-thing connections. Specifically, the 6G communication system would be able to provide services, such as truly immersive extended reality (XR), high-fidelity mobile hologram, and digital replica. Further, services, such as remote surgery, industrial automation and emergency response would be provided through the 6G communication system thanks to enhanced security and reliability and would have various applications in medical, auto, or home appliance industries.
Meanwhile, a multi-subscriber identity module (multi-SIM) terminal capable of accessing a plurality of networks is becoming common. A modulator/demodulator (MODEM) of the multi-SIM terminal may independently access networks of a plurality of mobile communication providers at the same time by using a plurality of SIMS or a plurality of universal subscriber identity modules (USIMs), and thus improved user experience may be provided to a user. For example, in the MODEM of the multi-SIM terminal, one SIM may be used exclusively for calls and the other SIM may be used exclusively for a data communication, or a plurality of SIMS may be used instead of roaming service when moving between countries/regions to provide an optimized mobile communication service in a corresponding country/region.
The multi-SIM terminal may include a plurality of universal integrated circuit cards (UICCs) or embedded UICCs (eUICCs). Alternatively, a smart secure platform (SSP) terminal may support a multi-SIM by activating a plurality of telecom bundles.
Accordingly, studies considering various technical issues between a plurality of UICCs, a plurality of eUICCs, or a plurality of telecom bundles installed in an SSP and a multi-SIM terminal or a MODEM of the multi-SIM terminal are being actively conducted.

(1) Secure Medium (SE, eSE, UICC, eUICC, and SSP)
In various embodiments of the disclosure, a secure medium may include, for example, at least one of a secure element (SE), an embedded secure element (eSE), a UICC, an eUICC, and an SSP.
In various embodiments of the disclosure, the SE means a secure module including a single chip which may store secure information (e.g., a mobile communication network access key, user identify identification information such as an identification card/passport, and/or the like, credit card information, an encryption key, etc.), and include and operate a control module (e.g., a network access control module such as a universal subscriber identity module (USIM), an encryption module, a key generation module, etc.) using the stored secure information.
In various embodiments of the disclosure, the SE may be used in various electronic devices (e.g., a smart phone, a tablet, a wearable device, a vehicle, an Internet of Things (IoT) device, etc.), and provide a secure service (e.g., a mobile communication network access, payment, user authentication, etc.) through the secure information and the control module. The SE may be used as a term collectively referring to a UICC, an eSE, and a smart secure platform (SSP) into which the UICC and the eSE are integrated. A form of the SE may be divided into a removable SE, an embedded SE, and an integrated SE which is integrated into a specific element or an SoC, according to a form in which the SE is connected to or installed in an electronic device.
In various embodiments of the disclosure, the eSE means an SE which is embedded and fixed to the electronic device and used. Normally, the eSE may be manufactured for a manufacturer upon a terminal manufacturer's request, and may be manufactured to include an operation system (OS) and a framework. The eSE may remotely download and install an applet-type service control module, and may be used for various secure services such as an electronic wallet, ticketing, an electronic passport, a digital key, and/or the like. In various embodiments of the disclosure, an SE in a form of a single chip attached to an electronic device, the SE capable of remotely downloading and installing a service control module, is referred to as an eSE.
In various embodiments of the disclosure, a UICC refers to a smart card inserted into and used in a mobile communication terminal, and/or the like. The UICC may include an access control module for accessing a network of a mobile communication provider. The access control module may include, for example, a USIM, a subscriber identity module (SIM), an Internet Protocol (IP) multimedia service identity module (ISIM), and/or the like. A UICC including a USIM is generally referred to as a USIM card. Likewise, a UICC including a SIM is generally referred to as a SIM card.
The SIM may be included in a UICC when the UICC is manufactured, or the SIM of a mobile communication service that a user desires to use at desired time may be downloaded in the UICC. The UICC may also download and install a plurality of SIMs, and may select and use at least one of the plurality of SIMs. The UICC may be fixed to the terminal and used or may be used in a removable form, according to a form factor.
A UICC embedded in a terminal as a chip form and used is an eUICC, and particularly, a UICC embedded in an SoC including a communication processor (CP), an application processor (AP), or a single processor into which the CP and the AP are integrated may also be referred to as an integrated UICC (iUICC). Normally, an eUICC and an iUICC may be fixed to and used in a terminal, and access a network service of a mobile communication provider network by remotely downloading a SIM in the eUICC or the iUICC. The eUICC or the iUICC may be included in a specific SIM embedded therein at the time of manufacturing, and may be embedded in a terminal. A form in which SIM information which is downloaded in the eUICC and used and authentication information for receiving a network service and information included in a USIM application are packaged in a software form may be an eUICC profile. The eUICC profile may be called an eSIM profile, an iUICC profile, or a USIM profile, or may be more simply called a profile.
In various embodiments of the disclosure, a smart secure medium, e.g., a smart secure platform (SSP) is a secure module capable of supporting functions of an UICC and an eSE in a single chip. The SSP may be classified into a removable SSP (rSSP), an embedded SSP (eSSP), and an integrated SSP (iSSP) embedded in an SoC of a terminal. The SSP may include one primary platform (PP) and at least one secondary platform bundle (SPB) which operates on the PP. The PP may include at least one of a hardware platform and a low-level operating system (LLOS), and the SPB may include at least one of a high-level operating system (HLOS) and an application which operates on the HLOS.
In various embodiments of the disclosure, the SPB is driven on the PP of the SSP by using a resource of the PP, and for example, a UICC bundle may be a form in which an application, a file system, an authentication key value, and/or the like, stored in an existing UICC and an OS, e.g., an HLOS, in which the application, file system, the authentication key value, and/or the like operate are packaged in a software form. In various embodiments of the disclosure, it may be noted that an “SPB” may be simply referred to as a “bundle.”
A bundle may access a resource in a central processing unit (CPU), a memory, and/or the like of a PP through a primary platform interface (PPI), and may be operated on the PP through this. A communication application such as a SIM, a USIM, an ISIM, and/or the like may be included in the bundle, and various applications such as an electronic wallet, ticketing, an electronic passport, a digital key, and/or the like may be included in the bundle.
An SSP may be used for UICC or eSE purposes according to a bundle remotely downloaded and installed, and may be used for the UICC and eSE purposes by installing a plurality of bundles in a single SSP and simultaneously operating the plurality of bundles. For example, if a bundle including a profile operates, an SSP may be used for UICC purposes to access a network of a mobile communication provider. The corresponding UICC bundle may operate by remotely downloading at least one profile, and select and operate one of the remotely-downloaded at least one profile, as with an eUICC or an iUICC. For example, if a bundle including a service control module including an application capable of providing a service such as an electronic wallet, ticketing, an electronic passport, or a digital key, and/or the like operates on the SSP, the SSP may be used for eSE purposes.
A plurality of service control modules may be integrally installed and operated in one bundle, or may be installed and operated in independent bundles. An SSP may be used by downloading and installing a bundle to be operated on the SSP in an external bundle management server, e.g., a secondary platform bundle manager (SPB manager) by using an over-the-air (OTA) technology. A method of downloading and installing a bundle by using an OTA technology in an SSP is equally applicable to an rSSP detachably inserted into a terminal, an eSSP embedded in the terminal, and an iSSP included in a SoC installed in the terminal.
In various embodiments of the disclosure, a telecom bundle may be a bundle which includes at least one network access application (NAA), or includes a function of capable of remotely downloading and installing at least one NAA. Here, the NAA is a module for accessing a network stored in a UICC, and may be a USIM or an ISIM. The telecom bundle may include a telecom family identifier indicating a telecom family.
In various embodiments of the disclosure, an eSIM bundle may be a bundle which has an eUICC OS driven therein and installs a profile in a terminal to operate a network service by performing the same function as an eUICC. The eSIM bundle may also be referred to as a Remote SIM Provisioning (RSP) bundle in consideration of the name of an RSP which is a major function of an eSIM. In various embodiments of the disclosure, the eSIM bundle may include a telecom family identifier indicating the eSIM bundle.
In the specification, an application protocol data unit (APDU) may be a message for a terminal or a controller in a device to interwork with an eUICC. The APDU is a pair of a command and a response, and an APDU command and an APDU response are defined in ETSI 102.221 with reference to ISO 7816. As defined in ETSI 102.221, the APDU command includes a class of instruction (CLA), instruction (INS), an instruction parameter 1 (P1), and an instruction parameter 2 (P2) as a header of the APDU, and includes Lc (number of bytes in a command data field), data, Le (number of bytes expected in response of the command) as a body of the APDU, the APDU response includes an optional data field, SW1 (status byte 1), and SW2 (status byte 2), and a detailed description thereof refer to the ETSI 102.221 standard.
In various embodiments of the disclosure, a profile package may be used interchangeably with a profile or may be used as the term representing a data object of a specific profile, and may be referred to as a profile tag, length, value (TLV) or a profile package TLV. A profile identifier may be indicated as an integrated circuit card identifier (ICCID) as a unique identification number of the profile. If the profile package is encrypted by using an encryption parameter, the profile package may be referred to as a protected profile package (PPP) or a protected profile package TLV (PPP TLV). If the profile package is encrypted by using an encryption parameter which may be decrypted by only a specific eUICC, the profile package may be referred to as a bound profile package (BPP) or a bound profile package TLV (BPP TLV). The profile package TLV may be a data set expressing information included in the profile in a TLV format.
In various embodiments of the disclosure, an authentication algorithm may be used, for example, an authentication and key agreement algorithm may be used.

An example of the MSMS may include dual-SIM dual-standby (DSDS) supporting a dual-SIM function with two SIM cards. The MSMS and the MSMA are in common in that a MODEM supports a plurality of logical basebands. The MSMS differs from the MSMA in that in a case of the MSMA, a plurality of transceivers support a network access to a plurality of networks which are completely separated from each other, but in a case of the MSMS, one transceiver shares a plurality of logical basebands with a time division multiplexing scheme to support a network access to the plurality of networks.
In various embodiments of the disclosure, one logical baseband may mean a network protocol stack which may perform a network access to a network (for example, a 3GPP network) based on one communication subscriber identifier information (for example, authentication information of an SIM). Digital information through a logical baseband may be modulated and the modulated digital information is transmitted through a transceiver as an analog signal form. An analog signal received through a transceiver is converted and modulated into a digital signal, and the digital signal may be decoded through a local baseband.

In various embodiments of the present disclosure, a multi-SIM MODEM may be connected to a plurality of physical SIMS, an eUICC, and a telecom bundle. The multi-SIM MODEM may include SIM ports, and the number of SIM ports is greater than or equal to the number of SIMs which the multi-SIM MODEM may support at the same time. In general, the number of SIMs which may be simultaneously supported by the multi-SIM MODEM may be related to the number of logical basebands which may be simultaneously supported by the multi-SIM MODEM. If the multi-SIM MODEM supports an MEP RSP bundle, the multi-SIM MODEM may include a separate SIM port for management for managing the MEP RSP bundle. This SIM port for management may be set to be accessible only by terminal software having authority to manage the MEP RSP bundle. In particular, a SIM port of a multi-SIM MODEM in an iSSP may be referred to as an iSIM port (iSSP SIM port).
The number of logical basebands which the multi-SIM MODEM may support simultaneously may be related to the number of telecom packages which the multi-SIM MODEM may support simultaneously.
In addition, an iSIM port may be seen as an independent SIM slot in a higher layer such as an OS/framework of a terminal. For example, according to the global platform open mobile API standard, the iSIM port may correspond to one card reader class. In addition, the iSIM port may be also used as a medium allowing a user in a user interface (UI) of the terminal to connect a specific bundle to a specific baseband and activate the specific bundle.
In various embodiments of the present disclosure, a multi-SIM MODEM having two independent logical basebands may have two or more iSIM ports, and likewise, a multi-SIM MODEM having an independent logical basebands may include n or more iSIM ports. For example, a multi-SIM MODEM supporting an MEP RSP bundle may support a total of 3 iSIM ports, including an iSIM port for managing the MEP RSP bundle. Similarly, a multi-SIM MODEM having an independent logical basebands may support a total of n+1 iSIM ports, including an iSIM port for MEP RSP bundle management.
In various embodiments of the present disclosure, a multi-SIM MODEM having two iSIM ports may simultaneously support two different UICCs, eUICCs, and telecom bundles, and likewise, a multi-SIM MODEM having n iSIM ports may simultaneously support n different UICCs, eUICCs, and telecom bundles. Here, the supporting means performing a network access by using authentication information within a UICC, an eUICC, and a telecom bundle to provide a communication service.

In operation 1012, the LBA 1002 transfers a first bundle activation command to an SPBL 1003. In operation 1012, for example, the first bundle activation command may be an Si3.EnableSpb command including an identifier of the first bundle identifier 1005.
In operation 1013, the SPBL 1003 activates the first bundle 1005 through a primary platform (PP) of an iSSP. An operation of activating the first bundle 1005 may be, for example, an operation of decrypting and activating an encrypted first bundle 1005 and moving up the same to a RAM. After the first bundle 1005 is activated, the first bundle 1005 may broadcast to other entities in the iSSP that the first bundle 1005 is activated. For example, the corresponding broadcasting may be performed through an entity called a network controller host in the iSSP.
As the first bundle 1005 is activated, a MODEM 1004 and the first bundle 1005 form a first APDU pipe in operation 1014.
In operation 1015, the MODEM 1004 transfers an identifier of the first APDU pipe to the SPBL 1003. Operation 1015 may be performed in connection with a network controller host (NCH) and a router which are entities in the iSSP.
In operation 1016, the SPBL 1003 may transfer a response to the first bundle activation command in operation 1012 to the LBA 1002. if the first bundle 1005 is successfully activated and forms the first APDU pipe with the MODEM 1004, the response in operation 1016 may include a first APDU pipe identifier. The LBA 1002 may identify the identifier of the first APDU pipe formed for the first bundle 1005 activated in operation 1012 to communicate with the MODEM 1004 based on the first APDU pipe identifier received from the SPBL 1003.
In operation 1017, the LBA 1002 transmits an APDU pipe-to-iSIM port mapping request to the MODEM 1004 to map the first bundle 1005 to the iSIM port 1 in the MODEM 1004. The corresponding APDU pipe-to-iSIM port mapping request may include an identifier of an APDU pipe and an identifier of an iSIM port to be mapped. If there is no direct data transfer route between the LBA 1002 and the MODEM 1004, operation 1017 may be performed via the SPBL 1003. In this case, the LBA 1002 may transfer the APDU pipe-to-iSIM port mapping request to the SPBL 1003, the SPBL 1003 transfers the same to the MODEM 1004, and thus the identifier of the APDU pipe and the identifier of the iSIM port to be mapped may be transferred to the MODEM 1004.
In operation 1018, the MODEM 1004 maps the iSIMport identifier and the APDU pipe identifier transferred in operation 1017. Operation 1018 may be an operation of connecting a bundle (the first bundle 1005) connected via an APDU pipe (the first APDU pipe) having the transferred APDU pipe identifier, among APDU pipes formed by the MODEM 1004 with a logical baseband associated with the transferred iSIMport identifier. For example, operation 1018 may be an internal operation of the MODEM 1004, which allows a network access through a logical baseband associated with the iSIMport identifier by utilizing a K value and an IMSI of the first bundle 1005. Through operation 1018, activated telecom bundles may be connected to a specific logical baseband in the MODEM 1004 to perform a network access.
In operation 1019, the MODEM 1004 may respond with a result of the execution of operation 1018. Through operation 1019, the LBA 1002 may recognize that the first bundle 1005 is successfully mapped to the iSIMport which corresponds to the iSIMport1ID.
Operations 1021 to 1029 show a procedure of activating the second bundle 1006 and mapping the same to an iSIMport2. Operations 1021, 1022, 1023, 1024, 1025, 1026, 1027, 1028, and 1029 may be performed with reference to operations 1011, 1012, 1013, 1014, 1015, 1016, 1017, 1018, and 1019, respectively.

For example, the user 1001 may intend to activate the first bundle 1105 in an iSIMport 1.
In operation 1112, the LBA 1102 transfers a first bundle activation command to the SPBL 1103. In operation 1112, for example, the first bundle activation command may be an Si3.EnableSpb command including an identifier of the first bundle 1105 and an identifier of the iSIMport1.

In operation 1117, the MODEM 1104 may perform the iSIM port-to-APDU pipe mapping. According to an example in
In operation 1118, the MODEM 1104 may inform the SPBL 1103 of a result showing that operation 1117 is successfully performed.

In addition, a snapshot of the SIM card manager UI 1501 is a snapshot in a case that an installed subscriber list 1505 including profiles within a telecom bundle or an RSP bundle installed in an iSSP in the secondary slot 1503 is opened, and then a communication service of a second communication provider is selected.
In
In operation 1531, a communication provider to be used in the primary slot 1502 and the secondary slot 1503 is selected through the SIM card manager UI 1501. In particular, a snapshot of the SIM card manager UI 1501 in
According to operation 1532, the SIM card manager 1511 determines whether to activate a standalone telecom bundle, whether to activate a profile installed an RSP bundle, or whether to activate a profile installed in an MEP RSP bundle in order to use a communication service of a selected communication provider. In addition, in a case that a bundle or profile of a communication provider other than the communication provider selected through the SIM card manager UI 1501 in the secondary slot 1503 has been activated, the SIM card manager 1511 determines whether the activated bundle or profile needs to be deactivated. In an embodiment of the disclosure, in order to use the communication service of the second communication provider which is selected through the SIM card manager UI 1501, a second communication provider profile 1517 of an MEP RSP bundle 1516 needs to be activated. Accordingly, after activating the MEP RSP bundle 1516, the SIM card manager 1511 determines to sequentially perform an operation of activating the second communication provider profile 1517.
In operation 1533, the SIM card manager 1511 activates the MEP RSP bundle 1516 through an LBA. Thereafter, the SIM card manager 1511 activates the second communication provider profile 1517 by accessing an ISD-R of the MEP RSP bundle through an LPA and transferring an ES10c.EnableProfile command.
In operation 1534, the activated second communication provider profile 1517 is connected to a second base band 1513 which corresponds to the secondary slot 1503. Here, in operation 1534, when the MEP RSP bundle is activated, the second communication provider profile 1517 to be activated later may be automatically connected to the second baseband 1513 by activating the MEP RSP bundle in conjunction with the secondary slot 1503 or the second baseband 1513. Alternatively, in operation 1534, after being activated without being connected to a specific baseband, the MEP RSP bundle 1516 may activate the second communication provider profile 1517 by including a SIM port identifier of the secondary slot 1503 or information related to the second baseband 1513 in a command for activating the second communication provider profile 1517. Alternatively, in operation 1534, a UICC APDU pipe between the MEP RSP bundle 1516 and the second baseband 1513 may be generated and allocated to the second communication provider profile 1517.

An operation of determining whether to activate a telecom package shown in
In operation 1601, the terminal detects that information about a telecom package of a communication provider to be activated and an iSIM port in which the corresponding telecom package needs to be activated is inputted. The information about the telecom package of the communication provider to be activated and the iSIM port in which the corresponding telecom package needs to be activated may be inputted, for example, through a UI, the telecom package of the communication provider to be activated may be referred to as a target telecom package, and the iSIM port in which the target telecom package may be activated may be referred to as a target iSIM port.
In operation 1603, the terminal determines whether another telecom package which has been activated already exists in the target iSIM port detected in operation 1601. If the other telecom package which has been activated already exists in the target iSIM port, the terminal deactivates a telecom bundle which corresponds to the other telecom package already activated in the target iSIM port in operation 1605. That is, in operation 1605, the terminal deactivates a profile which corresponds to the other telecom package already activated in the target iSIM port regardless of whether the other telecom package already activated in the target iSIM port is included in a telecom bundle different from the telecom package to be activated, or whether the other telecom package already activated in the target iSIM port is included in the same telecom bundle as the telecom package to be activated.
Contrary to this, if there is no other telecom package already activated in the target iSIM port, the terminal activates the target telecom package in the target iSIM port in operation 1607. If the target telecom package is a telecom bundle, the terminal transfers, to an iSSP, an Si3 command for activating the corresponding telecom bundle in the target iSIM port. If the target telecom package is a profile, the terminal determines whether an eSIM bundle including the target telecom package is activated. If the eSIM bundle including the target telecom package is not activated, the terminal activates the eSIM bundle and then activates the target telecom package.
Referring to
In operation 1612, the terminal determines whether the target telecom package is a standalone telecom bundle. Here, the standalone telecom bundle may not be an eSIM bundle, but a telecom bundle which may be one telecom package itself.
If the target telecom package is the standalone telecom bundle, in operation 1613, a telecom bundle which corresponds to the target telecom package is activated in a target iSIM port. In operation 1613, if there is another telecom bundle which has been already activated in the target iSIM port, the terminal may deactivate the telecom bundle which has been already activated. That is, in operation 1613, if there is the other telecom bundle which has been already activated in the target iSIM port, the terminal deactivates the telecom bundle which has been already activated and then activates a telecom bundle which corresponds to the target telecom package in the target iSIM port.
If the target telecom package is not the standalone telecom bundle, in operation 1614, the terminal determines whether the target telecom package is a profile included in a single enabled profile (SEP) eSIM bundle installed in the iSSP. Here, the SEP eSIM bundle may be an eSIM bundle without an MEP function.
If the target telecom package is the profile included in the SEP eSIM bundle, in operation 1615, the terminal determines whether the corresponding SEP eSIM bundle is activated in the target iSIM port.
If the corresponding SEP eSIM bundle is activated in the target iSIM port, in operation 1616, the terminal transfers, to the SEP eSIM bundle, an ES10c.EnableProfile command for activating a profile which corresponds to the target telecom package to activate the corresponding profile.
Alternatively, if the corresponding SEP eSIM bundle is not activated in the target iSIM port, in operation 1617, the UE activates the SEP eSIM bundle in the target iSIM port. In operation 1617, if there is the other telecom bundle which has been already activated in the target iSIM port, the terminal may deactivate the telecom bundle has been already activated. That is, in operation 1617, if there is the other telecom bundle which has been already activated in the target iSIM port, the terminal deactivates the telecom bundle has been already activated and then activates the SEP eSIM bundle in the target iSIM port. Then, the terminal activates the target telecom package again in operation 1616.
Alternatively, if the target telecom package is neither the standalone telecom bundle nor the profile included in the SEP eSIM bundle, in operation 1618, the terminal determines whether the target telecom bundle is a profile included in an MEP eSIM bundle installed in the iSSP.
If the target telecom bundle is the profile included in the MEP eSIM bundle installed in the iSSP, in operation 1619, the terminal determines whether an MEP eSIM bundle including the target telecom package has been already activated in the target iSIM port. In operation 1619, the terminal determines whether one of eSIM ports generated by the MEP eSIM bundle is connected to the target iSIM port.
If the MEP eSIM bundle including the target telecom package has been already activated in the target iSIM port, or if one of the eSIM ports generated by the MEP eSIM bundle is connected to the target iSIM port, in operation 1620, the terminal activates the target telecom package in an eSIM port of a target MEP eSIM bundle associated with the target iSIM port. Here, a command used for activating the target telecom package in the eSIM port of the target MEP eSIM bundle associated with the target iSIM port may be ES10c.EnableProfile (a profile identifier corresponding to the target telecom, and an eSIM port identifier associated with the target iSIM port).
Alternatively, if the MEP eSIM bundle including the target telecom package is deactivated in the target iSIM port or the eSIM port generated by the MEP eSIM bundle is not connected to the target iSIM port, in operation 1621, the terminal activates the eSIM port of the target MEP eSIM bundle in the target iSIM port. In operation 1621, if the target MEP eSIM bundle is deactivated, the terminal may activate the target MEP eSIM bundle.
If the target telecom bundle is not the profile included in the MEP eSIM bundle installed in the iSSP, in operation 1622, the terminal may not match the target telecom package to any telecom bundle or profile installed in the iSSP, so the terminal performs an error handling operation.

An operation illustrated in
In operation 1711, a UI 1701 may be a SIM card manager UI of a terminal, and transfers a first bundle activation command to the LBA/LPA 1702 upon detecting a first bundle activation request. Here, an input detected in the UI 1701 assumes, for example, a case in which a communication provider line selected in the SIM card manager UI is associated with the first bundle.
Alternatively, it may be noted that operation 1711 may be instead performed by a SIM card manager as described in
In operation 1712, the LBA/LPA 1702 receiving the first bundle activation command from the UI 1701 transfers a first bundle activation command to the SPBL/PP 1703. The first bundle activation command may be Si3.EnableSpb. Alternatively, the first bundle activation command may include a bundle identifier of the first bundle.
In operation 1713, the SPBL/PP 1703 receiving the first bundle activation command from the LBA/LPA 1702 activates the first bundle 1705. The corresponding activation operation may be an operation in which the encrypted first bundle 1705 is decrypted within the iSSP and a state thereof is converted into a usable state.
In operation 1714, the multi-SIM MODEM 1704 and the first bundle 1705 generate an ISD-R APDU pipe. The ISD-R APDU pipe may be a UICC APDU pipe used for transferring a command to the ISD-R within the first bundle 1705.
In operation 1715, the multi-SIM MODEM 1704 may transfer a response informing that operations 1713 and 1714 are normally performed to the SPBL/PP 1703. For example, in operation 1715, the multi-SIM MODEM 1704 may transfer, to the SPBL/PP 1703, a response informing that the first bundle 1705 is activated and the ISD-R APDU pipe is generated.
In operation 1716, the SPBL/PP 1703 may inform the LBA/LPA 1702 that operations 1713 and 1714 are normally performed. For example, the SPBL/PP 1703 may transfer, to the LBA/LPA 1702, a response informing that the first bundle 1705 is activated and the ISD-R APDU pipe is generated in operation 1716. In operation 1716, the LBA/LPA 1702 may receive an identifier of the iSIM port connected to the ISD-R APDU pipe. The information received by the LBA/LPA 1702 may be any information capable of identifying the iSIM port.
In operation 1721, the UI 1701 may detect a profile activation request, and accordingly transfer a profile activation command to the LBA/LPA 1702. For example, operation 1721 may be an operation of activating a profile in the first iSIM port. Also, it may be noted that operation 1721 may be instead performed by the SIM card manager as described in
In operation 1722, the LBA/LPA 1702 may transfer a profile activation command to the first bundle 1705. The profile activation command may be ES10c.EnableProfile. The profile activation command may include an identifier of a profile to be activated and an identifier of an eSIM port in which the profile may be activated. The profile activation command may be transferred through the multi-SIM MODEM 1704.
In operation 1723, a profile APDU pipe (a first profile APDU pipe) may be formed between the multi-SIM MODEM 1704 and the first bundle 1705. The first profile APDU pipe may be a UICC APDU pipe capable of transferring an APDU to a profile. The first profile APDU pipe may be a UICC APDU pipe connected to an eSIM port identified by the identifier of the eSIM port included in operation 1722. In
According to operation 1724, a process of matching the profile activated in operation 1722 to the target iSIM port may be performed. In operation 1724, the LBA/LPA 1702 may transfer, to the multi-SIM MODEM 1704, an identifier of an iSIM port to which the profile activated in operation 1722 may be connected.
In operation 1725, the first iSIM port (iSIMport1) and the first profile APDU pipe may be connected. Operation 1725 may be an operation of connecting the identifier of the first profile APDU pipe generated in operation 1723 with the identifier of the first iSIM port identifier to manage the same inside the multi-SIM MODEM 1704.
Operations 1731, 1732, 1733, 1734, and 1735 may be an operation of activating another profile included in the first bundle 1705 in the second iSIM port (iSIMport2).
In operation 1731, the UI 1701 detects a profile activation request to activate the second profile in the second iSIM port, and transfers a profile activation command to the LBA/LPA 1702 correspondingly. Here, the profile activation request detected in operation 1731 may be a request to use a communication provider line which corresponds to the profile 2 in a location which corresponds to the iSIM port 2.
In operation 1732, the LBA/LPA 1702 may transfer, to the first bundle 1705, a command to activate the profile 2 in the eSIM port 2. The corresponding command may be ES10c.EnableProfile. The corresponding command may include an identifier of the profile to be activated and an identifier of an eSIM port in which the profile may be activated.
In operation 1733, a second profile APDU pipe may be generated between the multi-SIM MODEM 1704 and the first bundle 1705. The second profile APDU pipe may be a UICC APDU pipe connected to the eSIM port identified by the identifier of the eSIM port included in operation 1732. In
In operation 1734, the second profile and the second iSIM port may be matched. Operation 1734 may be an operation of matching the second profile and the second eSIM port in which the second profile may be activated. Operation 1734 may be an operation in which the LBA/LPA 1702 transfers, to the multi-SIM MODEM 1704, an identifier of the second profile, the second eSIM port, or the second profile APDU pipe.
In operation 1735, the multi-SIM MODEM 1704 may connect the second iSIM port and the second profile APDU pipe. Operation 1735 may be an operation of connecting the identifier of the second iSIM port with the identifier of the second profile APDU pipe generated in operation 1733 to manage the same inside the multi-SIM MODEM 1704.
